Title:
METHOD AND APPARATUS FOR DETERMINING DIRECTION OF WORK, AND WORK PROVIDED WITH DIRECTION-DETERMINING FUNCTION
Document Type and Number:
WIPO Patent Application WO2010110348
Kind Code:
A1
Abstract:
A direction-determining apparatus (11) determines the direction of a work (1), which has a passive tag type IC tag (4) fixed at a predetermined position on the surface and is a subject the direction thereof is to be determined. The IC tag (4) is provided with a substrate (5), an IC module (6), and an antenna coil (7) eccentrically disposed on the substrate (5). The direction-determining apparatus (11) is provided with an antenna (14) which communicates with the IC tag (4), and a determining circuit (15). In a state where the work (1) and the direction-determining apparatus (11) are positioned at predetermined communication positions, communication is performed between the antenna (14) of the direction-determining apparatus (11) and the antenna coil (7) of the IC tag (4), communication intensity during a time when the communication is performed is determined by means of the determining circuit (15), and the direction of the work (1) is determined. Thus, the direction of the work can be determined using, without a change, the communication function of the work provided with the non-contact type IC tag.
